• Use cases: RV winterizing, yard faucets, irrigation zones, garden hoses
• Material: Copper, corrosion-resistant; color: yellow

Package includes: 1 pair (2 pcs) RV/Sprinkler blowout adapters

Quick Winterizing Steps

1. Turn off water supply; open downstream faucets/valves to relieve pressure.
2. Attach the adapter’s 3/4" GHT end to the hose bib, RV inlet, or sprinkler blowout port.
3. Connect your air hose to the 1/4" quick plug on the adapter.
4. Set compressor to a low starting pressure and increase gradually as needed. Do not exceed the pressure rating of your system/components.
5. Blow out lines zone-by-zone or fixture-by-fixture until only air exits; close valves as you proceed.
6. Disconnect, cap/close ports, and leave faucets slightly open if recommended for your system.
